UNITED STATES WILLIAM ZELLNER, OF PATERSON, NEW JERSEY, ASSIGNOR TO THEGON- SOLIDATED SAFETY VALVE COMPANY, OF BOSTON,-MASSAGHUSETTS.

NOlSE-QUlETING STEAM-NOZZLE.

SPECIFICATION forming part of Letters Patent No. 227,341, dated May 4,1880.

Application filed October 14, 1879.

To all whom it may concern 1 Be it known that I, WILLIAM ZELLNER, ofPaterson, in the county of Passaic and State of New Jersey, haveinvented a new and useful Improvementin Noise-Quietin g Steam-Nozzles;and I do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,forming a part of this specification,

in which- Figurel represents an elevation, and Fig. 2 a central verticalsection, of a device embodying my invention.

The object of this invention is to subdue the r 5 noise of escapingsteam.

The invention consists in constructing an escapepipe nozzle or chamber,through which the steam passes in its passage-to the atmosphere, withinternal deflecting plates or parti 2o tions that form a circuitouspassage therethrough and subdivide the escaping steam by interposedwire-gauze, perforated plates, or other porous material.

In order that others may understand and use my invention, 1 will firstproceed to describe the construction and operation of a device embodyingthe same, and subsequently to define in the claims the novel featuresthereof.

In the drawings, A represents a hollow cyl- 0 inder 9r case, providedwith fixed heads a at, having central openings 1) b for the inlet andexit of the steam. v a

The head a is provided with a projecting horizontal flange, 0, to beconnected to a cor- 3 5 responding flange upon an escape or exhaust pipeof the boiler, the central opening b forming the inlet-passage to -theinstrument.

The opening I; is surrounded by an inwardlyprojectingcone-shaped'nozzle, (1, its apex form in g a contracted passage for thesteam.

0 represents a hemispherical plate of somewhat larger diameter than theopening at the inner end of the nozzle-d, and located directly above thesame, the base of the hemispherical 5 plate 0 being in line with theinner end of the sides of the case A, having a passage, 12, for thesteam that is directed thereto by the hemispherical plate 6. This plate6 is also provided with a central opening, h, through which a portion ofthe steam is allowed to pass.

The opening it is covered by a cap, 0', corresponding in shape to theplate 0, and afflxed thereto by stud-bolts k k, to form an annularpassage over and around the top'of the plate 0.

mm are deflecting-plates, arranged horizontally, as shown, the plate mhaving a central opening for the passage of the steam, and the plateaumade solid and shortened to leave an annular passage, a, between it andthe case A, similar to the arrangement of the flange 9 upon thehemispherical plate e.

0 represents a series of'wire-gauze partitions, arranged verticallybetween the deflectingplates m m and flange g, and with intermediatespaces, as shown. These partitions areinterposed to fill the circuitouspassage formed bythe deflecting-plates for the purpose of subdividingthe steam. Any number of suchpartitions may be introduced to make up therespective series, and any suitable material that will permit thepassage of the steam in a divided state may be substituted therefor.

The exit-opening b is fitted with a short pipe, 12, extending throughthe head a, projecting outward and provided with a flared end, and alsoprojecting within the case or cylinder, as shown. Theinwardly-projecting portion of this pipe may also contain a series ofperforations, i, as shown, to continue-the subdividing process up to thepoint of the final exit of the steam to the atmosphere.

S represents a perforated plate, which serves to cover a portion of theannular space surrounding the nozzle d, and within which waterproducedby condensation of the steam may lodgeand be withdrawn throughthe pipe 10.

The operation of my invention will be readily appreciated by aninspection of the relative arrangement of the parts and composition of Ithe substance interposed within the circuitous nozzle (l and forming anannular passage, f,to the interior of the case or cylinder A, asindicated by the arrows, Fig. 2. p The hemispherical plate 0 isalsop'rovided with a surrounding 5o horizontal flange, 9, that extendsnearly to the passages for subdividing the escaping steam withoutfurther explanation, the efl'ect of such a result being authenticated byvariously-contriveddevices involving the same principle.

Therefore,

IOG

Having thus fully described my invention, What I claim, and desire tosecure by Letters Patent,'is-

l, A pipe, nozzle, or chamber for the passage of escaping steam,provided with internal pro.- ject-ing plates, forming a circuitouspassage therethrougl and having one or more interposed Verticalpartitions, composed of wiregauze, perforated plates, or other porousmate rial, whereby the escaping steam is separated or divided, for thepurpose specified.

2. A pipe, nozzle, or chamber for the passage of escaping steam,provided with an inwardly-projecting nozzle, (1, forming theinletpassage, a hemispherical deflecting-plate, 0, having a projectingflange, g, one or more horizontal deflecting-plates, m m, forming acircuitous passage therethrough, and one or more series of interposedpartitions, composed of wire-gauze or analogous material, whereby the 20escaping steam is subdivided, for the purpose specified.

3. The hemispherical plate e,. having the central aperture h, incombination with the cap 0, whereby a passage is formed for a di 25vided portion of the steam, for thepurpose specified. I I

,4. The exit-opening b, fitted with a pipe, 1), projecting within andbeyond the head a, and

'withor without the perforations r, substano tially as set forth.

WILLIAM ZELLNER.
